To allwhom it may concern:

Be it known that we, DALTON K. WILsoN and CLINTON O. BUTLER, citizens of the United States of America, and residents of Waterloo, Blackhawk county, Iowa, have invented certain-newand useful Improvements in Manure-Spreaders, of which the following isa specification.

Our invention relates to improvements in manure spreaders, and the ob ect of our improvement is :to furnish a-convenient, simple and inexpensive adjustable deviceade ted to disengage thexiriv' sprocket-ohain 'rom the-:drivmgs rocket-w eel -tost,op the rotaeater;-- drum. This object we have accomplished by-the-.-mehanism*which is hereinafter fully described and claimed, and which is illustrated in theaccompanying drawings, in which:

Figure lis a left side elevation of our improved device as applied in themechanism of a manure,-spreadermi Fig side elevation ofsaid device'on a manurespreader. Fig.3 ,is an, enlarged detail view ,of'the left-sideparts of'the' evice, showing a variation ofon'e-of the parts from that Shown-in Fi 1. Fig. 4:is.-an-enlarged perspective-oft e swing-arm for;su portingthe forward end-of thedrivi-ngsproc et-chain.

Similar numbers refer to similar parts.

throughout'the several views.

We have shown an ordinary form of-rrr anureaspreader 110x15, which may -be-removably supported on-the-bolsters of the .axles of the forward and rear-carrying wheels 20 and 22 res ectively. Such spreader is furnished wit a longitudinally-movable apron 13, and a beater-drum 1, the latter mounted on a rotatable transverse shaft 37 Whose ends are mounted in and project laterally from bearings which are bracketed to the sides of the rear end of the s reader-box 15. To the es of each rear carryinga large driving sprockettodrive the side.

Wheel 22 is secure wheel 21, ada ted chai 3 on are a driven s rockets wheel 2 secured to aprojecting en -of the shaft 37 oneach side.

The numeral 4 designates-a lever on each .2 isa-right-hand sprocket- The rear portion of side of the machine, whose rear end is .ineach case exteriorly threaded to fit an ,interiorly threaded socket 27 with a lock-nut 28-thereon.for purposes of longitudinal adjustment. Each socket 27-has an eye 33 at its rearend by which it is pivoted on a headed -stud 23 on the rear'end of each-side ofthe box :15.

he numeral 6 designates a casting, adapted to be secured to the forward end of each 1ever-4 by a pin or bolt'36. The forward part of-each of the castings-6 is bifurcated fora urpose to be presently described. Each casting 6 hasa transverse cylindrical bearing-opening 41 adapted to act -as-a slidewayafor-the short -shaft"5,';-Wi1'ich the outer portion ofeach short shaft 5 an idler 24 is rotatably but non-slidably mounted, and carries the forward end of-the s rocketchain 3 on the same side. The object ofv the lateral adjustments of--the canthusbe adjusted-laterally and securedin 1 its adj usted position by a-set-screw 29. ()n

In- Figs. 1 and 3 .are. shown twomethods of elevating. the sprocket-chain- 3, the .simpl st bein depicted in Fig. 3, but the device shown in Fig. 1 employing the same princi le of operation, but having a variation esigned to. obviate a dead-center.

, Referring first to Fig. 3, the forks of the casting 6 are shown as having registering perforations 30, adapted to receive in connection with one of the openings 35 in the embraced link 25 a pin or-pivot-bolt 34. The link 25, there being one on each side of-the box 15, has a plurality of openings 35, whereby-when the wagombox 15 is-trarnsiferred from one-set-of runn' -.gearto an-.

other havingbolstersof a di extent-height, the adjustment may 'be -made to keep :the

In ii manure spreader, in. combination, rock-shaft 9, the letter extending t1nnsn wagon-hon reinovzihly mounted on. carryversely under the box. 15 with. its en s mounted in hangers 12. 'Vi hen the shaft 9 is rocked in one direction, by means of the said connections the arms l with the idlers 24 and the chains are elevated out of om ntive engagement with the driving sprockev wheels 21. i i lien the shaft is nicked in the reverse direction, the chains 3 are lowered into driving contact with said sprocket-wheels.

A hand-lever 23 has t lower end pivote on a. stud 38 extendin r. 'oni the lorwnrd port of the left-hand side ol t ie box 15, and Works within 1r rack-bar 19 adopted to limit its forward and back movements. A. connectingrod ll has its for rd end pivolslly connected on a. stun on the .cver 18, while its rear end has n pivotal connection 1G vvilh the end of an arm 31 secured to the left-hand end of the rocloshnft 1? this izlilS the shaft 9 may he rocked forward or back to raise or lower the chains In order to prevent any incon nsnicncc arisingfrom a possible dean-center, we n ve shown in Fig. 1 s modification designed to eliect that purpose. For the arm 3] is substituted. a lever 8 pivoted intermedizu;ely "lo the wagon-box on a stud The lower end of said lever is formed into a toothed sector 39 whose teeth are adopted to engoqe and. intermesh with a plurality of similar tee-ti 40 formed on the hub of the arm 10. The action of the lever 1.8 is thus of course reversed in its action on the chains 3, from what it is in the device shown in Fig. 3, but the result of the extra leverage thus introduced between the pivotal points 16 and 11 is to prevent a,

stoppage on a. (lend-center.
